摘要 把热电制冷的机理与一般相变制冷的机理作比较 ,分析热电制冷过程的热力学原理。由分析结果得知 ,在理想工作条件下 ,电流通过半导体材料进行制冷时 ,同时存在的帕尔帖效应、汤姆逊效应和傅立叶效应三种效应共同耦合作用的制冷效果可以分解为电子循环与两种不可逆效应的叠加。其中的作用力是二种材料的电子化学势 。 Based on thermoelecric refrigeration theory , the paper made some emphasis on the deduction of electron chemical potential and gives comparison on mechanisms between the thermoelectric cooling and normal phase change cooling, analyzing the basic thermodynamic principles of the thermoelectric cooling.
